2 .s cinese The thread connectingv device lt-secures the thread to the needle 7, as will be hereinafter described. lfpon each forward movement of the operating lever, the jaws 6 are closed and the needles 7 pase through themantle and said jaws am ut the same time the thread is cut and connected to the said needles; upon each backward movement of the lever the revolving thread carrier and t0 s acer is rotated one-halt revolution in the rrrection as indicated inFig. 2, and. the thread is drawn through the mantle as will be clearly manifest. The needles 7, are secured to a holder t), b v means of a grooved-bar 37,

which is secured in a proper tion by means of a screw as shown. clear y m Figa. t and 4. The member 2U, ur alwfsceured to the holder 0 and forms a cam to cooperate with the jaws 6 or closing the rame as the lever 4 is moved in a forward direction. When the member 20 has cleared the bent portions of the jaws 6, said jaws 6 are moved their furthest outward positron so as to allow the core jaw 3 to receive thev mantle as 26 will be clearly manifest.

he onder side of the holder il, is eonntrncted ao as to tit aml travel within u slot 35 of the toble A. and is connected to the o reratin lever 4 by means of o link -t-t as 30 srown eearly in Fig. 5. The guide S' extends vertically through the rdot nud is provided with openings through which the needles? are dem ned to pass. thnt is. upon the forward stro e of soid lever; the said 35 guide S' is made integral with t-lre purt 43 which slides backward and forward in the member ns elearlv shown in Fig. tl.

when the lever 4 in moved inthe direction to clone the jow ti, the guide is slightly 40 moved in the nome direction, b v preneur-e of the needle T, when in the act of making no v insertion in the muntle: this guide is limited in this movement by the core jou' Il.

Tharlpride t4' la sllghtl' moved inthe oppo site t ireetion, when tie needles are in the act of drawing the asbestos rhrend thi-oooh the montle,v especinlly when approaching the completion ol drnwlng-the trread through v the mantle.

Nr he connecting device ll, ia imparted o t oscillatory movement whenl the leverrs moved in a direction to close the jawn 0 l by means of a bar l0, pressing down upon the arm il of the sind connecting device,

a'aimrt the tension of. the spring 40, ae s town in Figs. 4 and 8, and when pressure is relieved upon the arm ll, the connecting device vwill return to its normal position.

'l3 designates a portion of the thread guiding device which guides the threadh from the revolving thread carrier and s'pacer.' To revolve the thread carrier, a s'purgear 3l) ie designed to engage a rack 34, asclearly illustrated in Figs.4 and 5; the rack 34 is con- 5 nected as at 34' to a slotted angle le er 28,

which is pivoted to the under aide of the table A, aml having one arm thereof, connected to the lever 4 by means of a link 27 as clearly shown in dotted lines in Figs. l oud 4. i4 is a ratchet arranged in auch wise 10 as to revolve the. member 5 a semi-revolution, at each backward movement. of the Y lever 4.

A shaft 30 is provided, which is'jonrnaled in bearin l5 upon which `the gear 30 and 76 and rate ret I4 are mounted. When the lever 4 is moved to open the jaws tl. the rack is moved in the direction of the spool of thread, which rack rotates the -ur 30, carrymg the awlg which enga t e ratchet t4, a0 w ich ing fixed to the s aft 88. causes the thread-earner to be revolved as will be clearly observed. Also journaled upon the shaft, in a ratchet. wheel 17, designed to be engaged b a s ring 16 so as to prevent retroab greesron o sait shaft, which, carries the said thread carrier and spacer; this thread carrier is sto pcd at a point where the thread is designer to be cut as shown in Fig. 4.

The rack 34,as it travels lateral v of the e0 trible A. is guided in said travel b means of a Y guide 38, as shown clearly in l'i 5. 'lhe lever -t is provided with a slot in w rich a pin 4" ie rnonnted, as clearly shown in Fig. this pin et' extends vertically through tht. se slot 48 of the table A, and is then connected to a portion of the thread cutter 24, as also shown in Fig. 4. 25 is a bracket which holds the thread cutter 24 in place and through which, it moves, and the top of which serves to releruse the member i9 from the notch of 'the member 20- as the said lever 4 is drawn 26 designates guiding elemente which arev connecter to ther b v means of a pin 20 105 which passes t iroughaslot 20l of the member 'zo this construction serves as a stop ing device for the member 2t), when release( as the spring 23 expands. 'lo hohl the member ttl in the noteh ot the member 20, a spring 18 is no pnlwrded as clearly shown in' Fig. 4. The lmie 2l which event the thread, is secured nt one end of the bor 24, ad'acentthe spring 23; the member 20, coopera es with the stem r ot the knife 21, and the spring 23 is designed lle lor the purpose of holding it lirnrly forward as will he ele riy manifest. As the members 20 and 46 ho d the thread while the knife 2l cuts lthe same, the revolving thread carrier and spacer restsagainst a member 22, as clearly shown in Figa. l and 4. Aa shown in `rg. 8 th'e thread connecting barl l0 is con.- neeted to the lever 4, said bar 10, is designed to move in a slot 32 in the table A, that is, when the operating lever 4 is moved forward 125 'and as said operatmglever is moved forward i the bar 20 contacts with the'element 11, which is held in a vertical position b v means;
